For the past six months The Sims 4 refuses to launch on my PC, throwing the “Game License Invalid” message every single time. I have not upgraded or altered the operating system, and the base game as well as all packs were bought directly through Origin (now EA). A full reinstall (including clearing the EA cache) made no difference, so I’m clearly missing something deeper in the license-validation chain. What I need is simple: locate the root cause of the license failure and get the game opening again through EA just as it used to. Whether that involves registry work, offline activation fixes, or account-level troubleshooting with EA servers, I’m open to anything as long as the end result is a clean, officially-recognized install that lets me play and update normally. Deliverables • Step-by-step actions you take (or have me take) • Confirmation that the game launches to the main menu without errors • Any preventive tips so the issue doesn’t return after future EA or Windows updates If you’ve solved this exact error before or know the ins and outs of EA DRM, I’m eager to get started right away.
